Week old 27-9 already rusting?

[GrinningDag]

I might be just panicking for no reason but I thought I should ask anyway.

I'm new to blued revolvers but I did prepare for the maintenance by purchasing a silicon cloth and I head eezox was pretty good so i got that for the gun. I oiled the gun for 4 days last week and only took it to the range once. I even keep it in a gun sock.

Today though while I'm admiring it I see a brown spot on the cylinder. Is it rust or something else? I noticed after firing at the range there were scorch marks left on the cylinder too. Are blued finishes really that sensitive?

Is this a new 27? I am not up on production numbers, but I have never seen happen what you are describing.

Now a word about oiling. There are a ton of products out there, but since 1970 I was shown the following. Get a piece of lambswool( REAL LAMBSWOOL), and treat it with Kellogs #110 or 105 pure silicone. This can be bought in most ace or true value stores.. Spray the lambswool ( about a 7" sq piece) well with the spray. Fold it over and work it in good. Then wipe the cleaned gun down. Put some on a patch for the bore if you like. The large spray cans 12 oz or so say 110 or 105 on them .. If you get the 4 oz can and it just says silicone it will be the 110. Kellogs products is in Sandusky Ohio. Never have I has a spot of rust in 50 years. Much better than a silicone cloth. the lambs wool gets into every crevice. Screw slots too. Kelloggs silicone only.. Can't vouch for the other stuff. It may say Kel 110 or 105 on the can. Read the label. Like I said 50 years, no rust. Retreat wool as needed

Yeah it's a current production Model 27, bought it new in box last week with no previous owner.

Thanks for the advice, I will check out the Kellogs spray can and get lambswool.

Not rust. Blast mark caused by gases rebounding off the scope mounting screw hole in the top strap. Should clean off, but will eventually leave a mark. Just part of the fun of shooting them. (Some folk plug the hole with a tiny screw, but it has to be dead flush on the bottom to work.)

ETA: Eezox is great for preserving, not so much for lubricating, BTW.

I would suggest wetting the entire gun with Water Displacing oil Number 40, yeah good old WD-40. Most folks aren't aware that this was a penetrating oil specifically developed to act as a rust preventative for Black Oxide finishes on steel. I'll also note that WD-40 is a pretty poor lubricant but an excellent rust preventative. If you really want to stop a squeak I would suggest a drop of 3 in One oil or Mobile One.

BTW, the difference between a Black Oxide finish and Bluing is that tools have Black Oxide and it's normally a hot dip process with no concern for a shiny surface, in terms for the chemistry of the finish both Bluing and Black Oxide are identical.


Anyhow after letting the WD-40 soak in for an hour or more then wipe the finish down to a dry appearance and then put on a layer of pure Carnuba Wax. Do this about every 6 months and rust should not be a problem unless you live on a salt water coastline, there once every month may be a good idea. Note, there are many premium brands of Boat or Car Waxes that are 100% carnuba and a bottle that will last for many years is relatively cheap.

Don't store it in a "gun sock"!

Typically a rust spot doesn't develop in a week on a new gun. Did you try and clean it off. Usually the finish has to be compromised in some manner before rust will take hold. Unless there was a nick in the finish, or a bubble some how under the finish I can't see how it would have rust already.

Gun socks will work fine if the gun is clean and has a coating of oil on it. If you're in a moist environment or the gun isn't cleaned before putting away I would avoid a gun sock. The oils from your hand are more likely to rust the gun over time than anything else.

As already mentioned, it is carbon scoring.

This is the same thing that happens to the front of your cylinder.

Use the same cleaning technique that use for your cylinder face

Personally I leave it alone on my shooters. Too much work to do every week for a cosmetic issue

It is carbon scoring. It is easy to remove if you put some Ballistol on the carbon spots and let it soak for about twenty minutes. Then just rub them off with a dry cotton cloth.
